The moisture contained in gaseous substances condenses on impact with colder surfaces to a greater of lesser extent, depending on the ambient conditions and in particular on pressure and temperature. If this occurs in the area of non-insulated electrical connections inside the generator, it is hardly possible to avoid electrical faults. Several cases of damage to power plant generators with similar causes and developments resulting from condensation as outlined above have provided grounds for the VGB Project Group on Generators to analyse the causes and compile recommendations for action to avoid such damage in future.

The basic international standards for reference designation provide users with generally applicable general rules and letter codes for main classes for the designation of technical objects and their documentation.

The standard for power plants establishes sector-specific specifications based on the basic standards, and also includes options to enable application for different power plant types.

The fulfilment of specific designation tasks and addressing of collections of information necessitates coding systems which establish a relationship between the object names and letter codes.

For the designation of power plant systems, table 3 of IEC 81346-2 provides a framework for the designation of "infrastructure objects". This Guideline, VGB-S-821-00-EN, assigns the power-plant-specific systems to letter codes based on this framework.

Remark: The VGB-Standard VGB-S-821-00-2016-06-EN replaces the publication VGB-B 101e. For existing applications the VGB-B 101e is still available.

Die internationalen Grundnormen zur Referenzkennzeichnung bieten den Anwendern allgemeingültige Grundregeln und Kennbuchstaben für Hauptklassen zur Kennzeichnung von technischen Objekten und deren Dokumentation.

Die Fachnorm für Kraftwerke trifft auf dieser Basis branchenbezogene Festlegungen, enthält aber ebenfalls noch Optionen, um die Anwendung für unterschiedliche Kraftwerkstypen möglich zu machen.

Zur Erfüllung konkreter Kennzeichnungsaufgaben und Adressierung von Informa-tionszusammenstellungen sind Kodiersysteme erforderlich, die die Namen der Objekte zu Kennbuchstaben in Beziehung setzen.

Zur Kennzeichnung von Kraftwerkssystemen bietet DIN EN 81346-2 mit Tabelle 3 einen Rahmen zur Kennzeichnung von „Infrastrukturobjekten“. Auf dieser Basis erfolgte in der vorliegenden Richtlinie VGB-S-821-00 die Zuordnung der kraftwerkspezifischen Systeme zu Kennbuchstaben.

Hinweis: Der VGB-Standard VGB-S-821-00-2016-06-DE ersetzt die Publikation VGB-B 101. Für bestehende Anwendungen verbleibt die VGB-B 101 weiterhin im Lieferangebot.

To detect incipient damage to generators in power plants, protective equipment is installed. For electrical protection, in 2012 VGB published recommendations in the VGB-Standard VGB-S-025 “Electrical Generating Unit Protection”. The VGBStandard in hand, VGB-S-164-11, shows the protective measures that can be taken when thermal limits are exceeded or leaks and other malfunctions occur. These protective measures relate to so-called thermal/mechanical generator protection and cover generators for thermal power plants, hydroelectric power plants and wind turbines.

As a result of particular impacts and stresses affecting reinforced concrete cooling towers and chimneys and strengthend by their special structures and conditions of operation, adequate instructions are required for contractors initially applying or renewing surface protection systems. This Guideline therefore takes the form of additional technical stipulations to supplement the existing standards and codes. In this spirit, the Guideline is intended to assist the customer as an aid to decision-making and a basis for inviting tenders, placing orders and performing work of this kind. The customer in this context may be the owner and/or operator or a company employed by these.

A1 Introduction: Le présent standard décrit comment bien surveiller les huiles usagées dans les installations avec turbines. Les huiles de turbines sont soumises, pendant le fonctionnement, à des modifications dues à des influences thermiques, chimiques, physiques et mécaniques. En principe, ces modifications ont pour effet d'altérer les propriétés d'une charge d'huile.

B1 Introduction:Le présent standard décrit comment bien surveiller dans les turbines les fluides difficilement inflammables à base d'esters phosphoriques. Les esters phosphoriques sont soumis, pendant le fonctionnement, à des modifications dues à des influences thermiques, chimiques, physiques et mécaniques. En principe, ces modifications ont pour effet d'altérer les propriétés d'une charge de fluide.

On the basis of the established practices in German nuclear power plants, and making allowance from the VGB “Concept for the Implementation of Tools for Professional Conduct”, the WG has worked out the principles for such training (target group, contents, training intervals, etc.) and written them down in this VGB-Standard.

Rather than sharing generally known theories and fundamentals on leadership behaviour, the VGB-Standard VGB-S041 is meant to serve as a basis for operator-specific requirements for leadership behaviour and focus content-wise on essential tasks of managers in day-to-day business.

Monitoring, limiting and protection devices must satisfy stringent requirements in order to afford safe and reliable operation of gas turbine units. The present revision was aimed at considering the present state of the art and the current codes of practice and ISO and VDMA standards. This Standard applies to stationary gas turbines (single-shaft and multi-shaft turbines) used to drive generators and other machinery.
